Casio Calculators / CE-515P Problem
« on: September 02, 2023, 12:19:52 am »
I'm trying to use the Casio CE-515P plotter with my PC-E500S calculator and CE-130T RS-232 interface. I'm using a homemade cable which I triple-checked against the manual for correct connections. The plotter works fine when I use it connected to a parallel port on a PC but when I try to use it through its serial port, I get garbage. I've checked the OPEN statement on the calculator

OPEN"COM:1200,N.8.1" AS #1

and it seems to match the plotter's parameters.

My plotter's switch settings are SW-1 and SW-2 OFF, SW-3, SW-4, SW-5, SW-6 ON.

This should be 8 bits, RS-232C, CR/LF and RS-232C levels.

What might I be doing wrong?

TI-Nspire / Re: Is this forum dead?

TI will keep updating the OS and try to block Ndless. From my observations, it seems like it takes a considerable amount of work to find a loophole to install Ndless, and as the amount of people here gets ever smaller, the chance of finding a loophole will decrease. If Ndless isn't available on new calculators, there will be no new members, and C++ projects (which tend to be the most fun because they get the most out of the CPU) won't be usable, so no one will visit anymore. No GBA emulators, no crafti, etc.

In addition, nobody will create projects if nobody will use them. It seems like no one is downloading projects, which doesn't encourage programmers at all.

So can we officially wave goodbye to TI-Nspire programming? There doesn't really seem to be a good solution to revitalize this forum. It seems like TI-Nspire programming is a thing of the past now when smartphones are plentiful. It seems like the whole site, along with all the other calculator programming sites, will die pretty soon when people ditch calculator gaming in favor of smartphones.


The above was posted four years ago and still remains relevant today. ndless seems stalled. Has TI finally devised a way to keep them from cracking the OS? If so, then no one who buys a new Nspire or Nspire II will be able to run ndless. Interest will be limited to current users and that group will shrink as members go on to other things, die, or for whatever reason just don't care anymore. Naturally this is a downward spiral. Fewer users interested means that fewer developers will be willing to invest resources to come out with new software. Less new software means fewer users will be interested and so the cycle continues. My 2₵ YMMV.

HP Calculators / Re: Is 1▶a instead of a := 1 bad practice? (HP Prime)
« on: January 08, 2014, 04:58:11 am »
However, I was wondering if it was considered a bad practice in HP programming to use the STO symbol to store variables instead of the var := value syntax or if it was considered as fine?
I was wondering what is everyone thoughts about this?

I use the := since it's closer to other languages and it can be saved to a text file with no special fonts. The STO symbol doesn't always work well in text files. (Neither do the square root symbol, the less than or equal to symbol, etc.)
